GBAS Implementation Steps

operational concept

site survey for GBAS ground station (GNSS, VDB)

VDB frequency coordination, official approvals, site preparation

procedure design (final approach segment - FAS data, AIP)

factory acceptance testing (FAT)

GBAS ground station installation, configuration

ATC & maintenance interfaces (implementation, testing, training)

ground testing (IGM, GIMOS)

flight inspection (certified GBAS flight inspection aircraft)

site acceptance testing (SAT)

maintenance concept (spare parts, maintenance contract, …)

operational safety assessment

ATCO training (briefing)

technical & operational approval (facility approval, service approval)

→ EC Declaration of Verification

Monitoring Systems – IGM

Independent GBAS Monitor

2 different GNSS receivers (SF GPS & DF SBAS)

VDB ground station data link receiver

Online GBAS CAT I receiver simulation

Certified GBAS CAT I MMR

in mobile (laptop) or stationary configuration (server) to support

GNSS data recording (ICAO SARPs Att. D.11)

GNSS performance assessment (ICAO SARPs Att. D.12)

GBAS ground testing (ICAO Doc 8071 Vol. II, 4.2)

2005 IGM development started

2010 update of server & laptop HW & operating system

2011 GAST D update phase 1 (HETEREX)

handling of new GAST D message types

add online GAST D receiver simulation (algorithms TU

BS)

2012 GAST D update phase 2 (SESAR 15.3.6)

additional online tools to support GAST D validation

Monitoring Systems – GIMOS

GNSS Interference Monitoring System

programmable real time spectrum analyzer

TSO C-129 certified GPS receiver

embedded PC

to support mobile and stationary measurements of

GNSS interference (GPS NPA, SBAS, GBAS)

VDB interference (GBAS)

VDB field strength (GBAS)

1998 GIMOS I development started (GNSS interference)

2000 GIMOS II second generation introduced

2006 GIMOS II GBAS VDB capabilities added

2011 GIMOS III development started

improve performance for GAST D VDB measurements

(more than one VDB Transmitter)

new hardware (PC, spectrum analyzer)

update software capabilities

2014 GIMOS IV interference monitoring implemented12

VDB Measurements – VDB Transmitter Setup

VDB transmitter setup to support

Lab measurements

improve setup for unwanted emission & adjacent

channel measurements

(ground testing, type approval)

develop frequency coordination criteria

(SESAR 15.3.6)

Site measurements

Munich 2010 – VDB site survey for GBAS CAT I

(ground & flight measurements)

Frankfurt 2011 – VDB ground coverage for GBAS

CAT II/III (GAST D, SESAR 15.3.6)

Zurich 2011 – support Skyguide in VDB site survey

for GBAS CAT I (ground measurements)

Frankfurt 2014 - VDB site survey for GBAS CAT I

(ground & flight measurements)

GBAS Ground Testing (Doc 8071)

GBAS ground testing divided into blocks

GNSS interference (GIMOS)

Survey of antenna phase center position

(geodetic equipment)

RF measurements (GIMOS)

VDB runway coverage & interference (IGM, GIMOS)

FAS data check on runway thresholds (IGM)

Performance evaluation & data content (IGM)

Matrix in DFS maintenance directive to allow more

flexible response to certain maintenance activities

GBAS Flight Testing – Flight Inspection Aircraft

GBAS CAT I flight inspection performed by FCS

(Flight Calibration Services, Braunschweig)

Certified flight inspection aircraft King Air 350

Certified flight inspection system (FIS)

modified GBAS MMR integrated

MMR guidance signal can be switched to

primary avionics incl. autopilot

FIS software is now GBAS capable

Licensed crew (pilots, FI engineer)

02/08/2011 First GBAS flight inspection in Europe

with certified aircraft, equipment and crew performed

in Bremen

GBAS Flight Inspection performed at Bremen,

Frankfurt, Braunschweig, Zürich, Malaga
